CYLINDERS
Cylinders
Carriage Cylinder
The carriage cylinder is located at the base of the inner
mast, and is a single acting ram type cylinder. Extreme
care should be taken when performing any type of re-
pair. In the event of excessive oil leakage around the
cap end of the cylinder or its inability to lift the load, the
cylinder will have to be removed from the truck and re-
paired.
Inspection
(Refer to Figure 15296)
1. Before disconnecting battery and initial cylinder re-
pair, a careful inspection should be made of the
cylinder assembly throughout a complete lift and
lower sequence.
2. Check roller bar or yoke area for signs of abnormal
wear, damage, etc.
3. Check ram (1) for any signs of nicks, scratches,
surface imperfections, etc. that allow abnormal
leakage, improper cylinder operation, or create
seal damage.
4. Check wiper ring (9) and complete cap area for
component wear and/or leakage that is abnormal.
As the cylinder assembly is repaired be aware of com-
ponent part condition and not only replace a worn or
damaged part, but correct or replace a part that may be
causing other premature wear.
